Abstract. Using cylindrical parameterization, the 3D mesh surface extracted from colon CT scan images is parameterized onto a cylinder, and afterwards visualized with a modified C...
The problem of deciding whether the edge-set of a given graph can be partitioned into at most k cliques is well known to be NP-complete. In this paper we investigate this problem ...
We study the parameterized complexity of an NP-complete geometric covering problem called d-dimensional Rectangle Stabbing where we are given a set of axis-parallel d-dimensional h...
The maximum independent set problem is NP-complete for graphs in general, but becomes solvable in polynomial time when restricted to graphs in many special classes. The problem is ...
We introduce the notion of views as a mechanism for securing and providing access control in the context of XML. Research in XML has explored several efficient querying mechanism...
